Description

Technical Field

[0001] This utility model relates to the field of continuous forming mold technology, and in particular to a continuous forming mold in-mold flipping mechanism. Background Technology

[0002] Continuous forming molds are a type of mold structure that uses multiple stations to continuously form parts from raw materials to finished products in a single mold. They are used in stamping, injection molding and other machining fields, and are especially suitable for mass production of small parts with relatively complex shapes and requiring multiple processing steps.

[0003] In the mass production of locking plate parts, burrs-free circumference is required to ensure assembly accuracy and safety. However, in traditional production, locking plate parts are processed using a continuous forming method, which produces burrs at the junction of the part and the strip. Traditional processes require a separate deburring step after continuous forming, which is inefficient. Therefore, a continuous forming in-mold flipping mechanism is needed to avoid missing steps and improve efficiency.

[0004] Early production of lock plate parts employed a separate process involving continuous forming dies and an independent deburring operation. The system consisted of a continuous forming die, a manual transfer device, and an independent deburring machine. Manual personnel transferred the cut parts from the forming die to the next station, where a grinding wheel or a dedicated chamfering die was used to remove burrs from the cutting edges. Because the continuous forming and deburring processes were separate, additional transfer time and equipment investment were required. Manual transfer also led to missed processes. To address these issues, existing technology added a deburring cavity, allowing the cut parts to be directly placed inside for deburring, improving efficiency and preventing missed processes. However, in practice, manually placing parts into the deburring cavity caused placement misalignment or inaccurate positioning, resulting in scrapped parts and failing to meet user requirements. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a continuous forming in-mold flipping mechanism, including a base 1, which serves as the mounting base for the entire mechanism. A flipping feeding mechanism 2 is provided on the top of the base 1, and a cleaning mechanism 3 is provided on the front right side of the top of the base 1.

[0034] The flipping feeding mechanism 2 includes a fixed plate 201, which rigidly fixes the servo motor 202. The bottom of the fixed plate 201 is fixedly connected to the top front side of the base 1, and the top of the fixed plate 201 is fixedly connected to the servo motor 202. The servo motor 202 can precisely control the rotation angle. The output end of the servo motor 202 passes through the front end of the fixed plate 201 and is fixedly connected to a rotating shaft 203. The rotating shaft 203 transmits the torque of the servo motor 202 to the fixed block 204 and the feeding rod 205. The fixed block 204 is fixedly connected to the rear side of the outer wall of the rotating shaft 203. The fixed block 204 rigidly transmits the rotational motion of the rotating shaft 203 to the feeding rod 205. The feeding rod 205 acts as a carrier for transporting parts, ensuring the feeding of materials. The rod 205 rotates synchronously with the rotating shaft 203. The left end of the fixed block 204 is fixedly connected to the material-pulling rod 205. The top left rear end of the base 1 is fixedly connected to the cutting die 206. The top right middle part of the cutting die 206 has a groove 207. The left end of the material-pulling rod 205 is fixedly connected to the electromagnet 208. When the electromagnet 208 is energized, it generates magnetic force to firmly attract the parts to the material-pulling rod 205. The outer wall of the electromagnet 208 is slidably connected inside the groove 207. The top left and right sides of the electromagnet 208 are fixedly connected to the positioning pins 209. The positioning pins 209 achieve precise positioning of the parts through mechanical cooperation. The top right rear end of the base 1 is fixedly connected to the deburring die 210. The bottom of the rear side of the outer wall of the rotating shaft 203 is provided with a precision detection component 211.

[0035] The precision detection component 211 includes a trigger piece 2111, which is used to trigger a detection signal. The left end of the trigger piece 2111 is fixedly connected to the right rear end of the outer wall of the rotating shaft 203. A support platform 2112 is fixedly connected to the middle of the base 1. The support platform 2112 ensures that the height of the sensor 2113 matches that of the trigger piece 2111. Sensors 2113 are provided on the top left and right sides of the support platform 2112. The function of the sensors 2113 is to detect the position of the trigger piece 2111 in real time.

[0036] A support plate 4 is fixedly connected to the top front side of the base 1. The support plate 4 reduces the radial runout of the rotating shaft 203 when it rotates at high speed. The outer wall of the rotating shaft 203 is rotatably connected to the inner side of the support plate 4.

[0037] The height of the cutting die 206 is higher than that of the deburring die 210. The top of the two sensors 2113 is at the same height as the bottom of the trigger piece 2111. The bottom of the outer wall of the rotating shaft 203 is rotatably connected to the top of the support platform 2112.

[0038] Specifically, after the continuous forming mold completes the part processing, the feed rod 205 and the electromagnet 208 are located inside the groove 207. The electromagnet 208 is de-energized, and the positioning pin 209 is inserted into the preset hole of the part. Precise positioning is achieved through mechanical cooperation to prevent the part from shifting. After the cutting process is completed, the electromagnet 208 is energized to generate magnetic force, which firmly attracts the part to the feed rod 205, ensuring that the part remains stable and does not shift during the subsequent flipping process. Then, the servo motor 202 drives the rotating shaft 203 to rotate, and the feed rod 205, carrying the part, is smoothly lifted from the groove 207 to complete the separation. The rotating shaft 203 continues to drive the feed rod 205 to rotate 180 degrees, moving the part from above the cutting die 206 to the pressing die. Above the burr lower die 210, during this process, the trigger plate 2111 on the rotating shaft 203 rotates with the shaft. When the part is accurately aligned with the burr lower die 210, the trigger plate 2111 simultaneously triggers the corresponding sensor 2113 on the support table 2112. The sensor 2113 feeds the signal back to the control system, and the servo motor 202 immediately stops rotating to ensure the accuracy of the flip angle and avoid angle deviation. After the electromagnet 208 is de-energized, the part is released and falls into the cavity of the burr lower die 210, ensuring that the burr can be accurately removed. After that, the feeding rod 205 resets. During the entire working process, the support plate 4 and the support table 2112 provide stable support for the rotating shaft 203, reducing the shaking during the rotation process and further ensuring the positioning accuracy.

[0039] Reference Figure 1 , Figure 2 and Figure 5 The cleaning mechanism 3 includes a connecting plate 301, which provides a rigid mounting reference for the sliding column 302. The bottom end of the connecting plate 301 is fixedly connected to the right side of the top front end of the base 1. The top of the connecting plate 301 is fixedly connected to the sliding column 302, which restricts the slider 303 to slide only in the vertical direction. The slider 303 is slidably connected to the outer wall of the sliding column 302. The function of the slider 303 is to drive the air blowing pipe 305 to move synchronously by sliding along the vertical direction of the sliding column 302, thereby achieving the air blowing position. The dynamic adjustment is achieved by connecting rods 304 fixedly connected to the left and right sides of the rear end of the slider 303. Air blowing pipes 305 are fixedly connected to the rear ends of the two connecting rods 304. The air blowing pipes 305 blow away the residual burrs in the cavity. The top of the base 1 is provided with an upper mold 306. The front right side of the upper mold 306 is rotatably connected to a transmission rod 307. The bottom end of the transmission rod 307 is rotatably connected to the top of the slider 303. The transmission rod 307 converts the vertical linear motion of the upper mold 306 into the forward and backward sliding motion of the slider 303.

[0040] Slide grooves 5 are provided on the left and right sides of the inner side of slider 303. The slide grooves 5 further constrain the movement trajectory of slider 303. Limiting blocks 6 are fixedly connected to the left and right sides of the outer wall of slide column 302. The opposite sides of the two limiting blocks 6 are slidably connected to the inner wall of the corresponding slide groove 5.

[0041] Guide posts 7 are fixedly connected to the four corners of the bottom of the upper die 306. Guide holes 8 are opened at the front and rear ends of the cutting lower die 206 and the deburring lower die 210 on the side away from the top. The outer walls of multiple guide posts 7 are slidably connected to the inner walls of the corresponding guide holes 8. The function of the guide posts 7 and the guide holes 8 is to ensure the verticality of the upper die 306 moving up and down.

[0042] A collection box 9 is fixedly connected to the rear right end of the base 1. The collection box 9 collects burrs in a centralized manner to prevent them from falling into the equipment. A dust collection hood 10 is fixedly connected to the top of the collection box 9. The dust collection hood 10 expands the collection range through a flared design.

[0043] Specifically, the cleaning mechanism 3 and the upper die 306 are mechanically linked via the transmission rod 307. After the deburring process is completed, the upper die 306 moves upward under the drive of the equipment, and the top of the transmission rod 307 rises synchronously. The rotational connection between the bottom of the transmission rod 307 and the top of the slider 303 causes the transmission rod 307 to drive the slider 303 to slide backward along the slide column 302 when the upper die 306 rises. The connecting rod 304 and the air blowing pipe 305 at the rear end of the slider 303 also move backward synchronously with the slider 303, ensuring that the air outlet of the air blowing pipe 305 is always aligned with the cavity of the lower die 210 for deburring. The sliding groove 5 on the inner side of the slider 303 slides in cooperation with the limiting block 6 on the outer wall of the slide column 302. The limiting block 6 acts as a guide. Conversely, when the upper mold 306 descends, the transmission rod 307 applies a pushing force to the slider 303, causing the slider 303 to drive the air blowing pipe 305 forward, thus leaving the mold working area. This ensures that the cleaning process starts immediately after the deburring process is completed, avoiding the delay of traditional manual cleaning. At the same time, the guide post 7 slides with the guide hole 8 of the cutting lower mold 206 and the deburring lower mold 210 to ensure the smoothness of the upper mold 306's ascent without shaking. The high-pressure gas blown out by the air blowing pipe 305 blows the residual burrs in the cavity away from the cavity. The collection box 9 at the rear right end of the base 1 forms a local negative pressure through the dust collection hood 10, which quickly sucks the blown burrs into the collection box 9.

[0044] Working principle: After the continuous forming die completes the part processing, the lower die 206 separates the part from the strip. At this time, the feed rod 205 and the electromagnet 208 are located in the groove 207. The electromagnet 208 is de-energized, and the positioning pin 209 is inserted into the preset hole of the part. Through mechanical cooperation, the part is precisely positioned to prevent it from shifting. After the cutting is completed, the electromagnet 208 is energized to generate magnetic force, which firmly attracts the part to the feed rod 205, ensuring that the part does not shift during the subsequent flipping process. Then, the servo motor 202 drives the rotating shaft 203 to rotate, and the feed rod 205, carrying the part, is smoothly lifted from the groove 207, completing the separation. The rotating shaft 203 drives the feed rod 205 to rotate. The material rod 205 continues to rotate 180 degrees, moving the part from above the cutting die 206 to above the deburring die 210. At this time, the trigger plate 2111 on the rotating shaft 203 rotates with the shaft. When the part is accurately aligned with the deburring die 210, the trigger plate 2111 simultaneously triggers the corresponding sensor 2113 on the support platform 2112. The sensor 2113 sends a signal to the control system, and the servo motor 202 immediately stops rotating to ensure the flipping angle and avoid angle deviation. The electromagnet 208 is de-energized and releases the part, which falls into the cavity of the deburring die 210 to ensure accurate deburring. Then the material rod 205 resets.

[0045] Furthermore, the cleaning mechanism 3 and the upper die 306 are mechanically linked via the transmission rod 307. After the deburring process is completed, the upper die 306 moves upward under the drive of the equipment. The transmission rod 307, which is rotatably connected to the right side of its front end, rises synchronously with the upper die 306. Since the bottom end of the transmission rod 307 is rotatably connected to the top of the slider 303, when the upper die 306 rises, the transmission rod 307 drives the slider 303 to slide backward along the slide column 302. The connecting rod 304 and the air blowing pipe 305 at the rear end of the slider 303 move with the slider. 303 moves backward synchronously, and the air outlet of the air pipe 305 is always aligned with the cavity of the lower mold 210 for deburring. The sliding groove 5 on the inner side of the slider 303 slides and engages with the limiting block 6 on the outer wall of the sliding column 302. The limiting block 6 plays a guiding and limiting role. Conversely, when the upper mold 306 descends, the transmission rod 307 pushes the slider 303, causing the slider 303 to drive the air pipe 305 forward and away from the mold working area, so that cleaning can be started as soon as the deburring is completed, avoiding the lag of traditional manual cleaning.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
